SULKY.

SPECIFICATION forming part of Letters Patent No. 265,C35, datedSeptember 26, 1882.

Application filed July 18, 1882.

To all whom it may concern:

Be it known that I, FrsHEn DOHERTY, a

citizen of the United States, and a resident of Grawfordsville, in thecounty of Montgomery and State of Indiana, have invented a new andvaluable Improvement in Sulkies; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 is a vertical longitudinal sectiona view of my improved sulky.Fig. 2 is a top view of the same; and Fig. 3 is a rear elevation,thewheels being removed.

This invention has relation to two-wheel carts or sulkies; and itconsists in the construction and novel arrangement of the self?adjusting side springs which support the seatbars, the shaft-springsconnected by arms to the seat-bars, and in the combination, with thewooden bow-support andthe transverse half-elliptic spring which isattached thereto,

of the self-adjusting side springs and the seatbars, all as hereinafterset forth.

In the accompanying drawings, the letter A designates the shafts, thecurved rear ends of which are fastened to the axle B.

(3 indicates the cross-bar between the shafts, and secured thereto byits ends.

D represents a curved bar or bow of wood, the ends of which are secured,by means of clip-bearings or fastening-plates, to the axle in such amanner that it extends transversely over the middle portion of the axle,its height being usually a little less than that of the shafts.

,E is the seat, and F the seat-bars, which extend forward and downwardtherefrom.

G is a transverse half-elliptic spring, which is fastened to the middleor highest part of the bow-support D. A

H designates the side springs, upwardly and rearwardly curved at theirfront ends and downwardly and forwardly curved at their rear ends. Theforward parts of these springs pass under the cross-bar C, whichconnects the shafts, and arefirmly clipped to said cross bar, and to thereverse bends a. of the springs (No model.)

in front the ends of the seat-bars F are bolted. The side springs extendfrom the cross-bar O upward and backward in curved'form under theseat-bars,forming elastic bearings for said bars, and thence extenddownward and rear- Ward in curved form, finally terminating in the undercurved ends, I), which are fastened to the ends of the half-ellipticspring G.

K represents a spring under each shaft.

One end of this spring is firmly fastened to the shaft, and to the freeend of the spring is I connected an arm, 0, which extends downward fromthe seat-bar. This shaft-spring and supporting-arm serve materially tostrengthen the seat when made double or for two persons. For singlesulkies it is not always used, as the side springs are so arranged withreference to the seat-bars that their contactsurface with said bars willbe increased with the weight of the load, and as theywill be therebysupported more and more as the weight is increased their self-adjustingpower will enable the sulky to accommodate itself to the difference inthe weight of single persons. As

the side springs lengthen under the weightof the load the bow-support Dwill move or bend backward to accommodate the increased length of thesprings. The seat-bars are designed to be connected to the side springsby leather straps, as indicated at at, so that the springs will haveeasy play.

L represents the foot basket or support which is sometimes used withvehicles of this character. Its ends may be connected to the sidesprings and half-elliptic spring. It braces 8 5 ends, in combinationwith the cross-bar (J and seat-bars F, substantially as specified.

2. In a sulky or two-wheel cart, the shaftsprings K and the arms 0,connecting the same to the seat-bars F, substantially as specified.

nation, with the bow-support D and the transverse half-e'lliptic springG, which is attached thereto, of the self-adjusting side springs and theseat-bars, substantially as specified.

4. The side sprihgs, H, clipped to the crossbar 0, and having theirupwardly-bent front ends, an, attached to the seat-bars, and their undercurved rear ends, I), attached to the half-spring G, substantially asspecified.
